However, according to the International Children's Continence Society (ICCS), nocturnal enuresis (NE) is defined as urinary incontinence during sleep in children aged 5 years or older [<span>3</span>]. Therefore, there has been little solid data or evidence regarding urinary symptoms or nighttime wetting before this age.</p><p>In this context, the present study provides valuable and timely insights using a large-scale national cohort that offers robust and reliable data [<span>4</span>].</p><p>The authors examined daytime bladder control at 2.5 years of age, bedwetting at 4.5 years, and the relationship between these two factors. They found that 82.8% of children were still using diapers at 2.5 years, and that the prevalence of bedwetting at 4.5 years was 42.2%. These findings, based on high-quality longitudinal data, shed light on an important but underexplored developmental stage that precedes the conventional definition of enuresis. Moreover, the authors demonstrated that incomplete daytime bladder control at 2.5 years was associated with an increased risk of the persistence of bedwetting.</p><p>The data were drawn from the “Longitudinal Survey of Newborns in the 21st Century,” a nationwide birth cohort conducted by the Ministry of Health, Labour and Welfare in Japan, including more than 30 000 children.

The present study provides timely real-world data directly comparing these two agents at equivalent daily doses of 50 mg, offering one of the few opportunities to evaluate their effectiveness and persistence under routine clinical conditions [&lt;span&gt;1&lt;/span&gt;].&lt;/p&gt;&lt;p&gt;A particularly notable finding is the relatively high discontinuation or switching rate observed among mirabegron users, with approximately 47.9% discontinuing the medication. The availability of vibegron as an alternative therapeutic agent likely contributed to this pattern, highlighting a prescribing dynamic that has not been previously captured in detail. The study thereby provides valuable insights into how the introduction of a second β3 agonist may influence clinical decision-making, adherence, and treatment persistence. The inclusion of sex-stratified analyses also enriches the study, offering more granular clinical information that may support individualized treatment selection.&lt;/p&gt;&lt;p&gt;Several randomized trials have compared mirabegron and vibegron in female OAB populations, generally demonstrating comparable overall efficacy, although vibegron may provide greater improvements in urinary frequency and urgency urinary incontinence in some cases [&lt;span&gt;2-4&lt;/span&gt;]. However, although several comparative studies have focused on female patients, direct comparative evidence in male populations remains extremely limited, making the real-world male-predominant data presented in this study particularly informative.&lt;/p&gt;&lt;p&gt;As expected in retrospective real-world research, several limitations should be acknowledged, including potential selection bias arising from clinicians' prescribing preferences and the absence of standardized criteria for determining treatment discontinuation. Confounding factors—such as comorbidities or prior treatment exposure—may also have influenced persistence outcomes. Nevertheless, the authors provide important observational evidence supporting real-world treatment behaviors, including frequent switching from mirabegron to vibegron (40.7%) and the contribution of having multiple β3 agonist options to extended overall β3 agonist persistence.&lt;/p&gt;&lt;p&gt;The authors' earlier work reported favorable long-term persistence with mirabegron before vibegron became available, and the current findings likely reflect the evolving therapeutic landscape. These results illustrate how the presence of multiple β3 agonist options may improve long-term management by enabling treatment switching rather than treatment discontinuation.
